Best ResponseYou've already chosen the best response.0above, 4 x 4 means 4 by 4, not 4 * 4, that looks confusing.

Best ResponseYou've already chosen the best response.0no of earthworm is proportional to the area of the plot 1000 ~ 4*4 (let ~ stand for proportional) now sides are 7 times longer (7*4)*(7*4) =7*7*(4*4) we already know (4*4)~1000 so =7*7*1000=49000
